BRAD FOR FASTENING WINDOW-GLASS.

Specification of Letters Patent.

Patented J nly 8, 1 913.

Application filed August 22, 1912. Serial No. 716,348.

To all whom/2'15 may concern:

Be it known that I, GOTTHELF M. NAU- MANN, a citizen of the UnitedStates, residing at Cleveland, in the county of Guy; hoga and State ofOhio, have invented certain new and useful Improvements in Brads forFastening l/ViIlClOW-GrlilSS, of which the following is a specification.

My invention relates to a glaziers brad or point adapted to fasten glassin wooden sashes, the same being a new article of manufacture and ale.

In the accompanying drawings, Figure 1 is a perspective View of the brador point alone. Fig. 2 is a direct perspective of a section of a windowsash s and two glasses edge to edge and a brad overlapping both glasses.Fig. 3 is a perspective view of a small section of a hot-bed sashwherein the glasses overlap from above and tend to slide down unlessspecially fastened by the brad.

The brad, point or fastener a is constructed as shown from sheet metal.and preferably of brass so as to make it durable and avoid the tendencyto rust which iron or steel are liable to. The said brad has a body 2, aV-shapcd driving point 3 at the middle of said body and right angledrearwardly bent wings or flanges t at its sides of the full width of thesaid body and of a depth relatively about as shown. The said point is ofless width at its base than the body of the brad as between its sidesand this leaves shoulders on the lower edge of the brad at each side oi.the base thereof which in any case is the driving limit of the brad, andthe said shoulders are flush with the lower edges oi the flanges t. Itfollows when the brad is driven its full depth into the sash that thesaid shoulder 5 and the lower edges of the flanges will alike bear onthe sash and serve as braces for sustaining the brad against the glass,especially when used as seen in Fig. 2. In Fig. 3 the glasses 6 overlapas usual in hot bed sashes and the brad is driven in laterally and oneof the flanges or lips l engages the edge of the upper sash and holds itin place. Both corners or an gles oi the said upper glass can befastened in the same way but in tact one brad for each glass suilices tohold the glass indefinitely.

In the manufacture the blank is struck iii-om a suitable piece oil sheetmetal and then the ends oi? the body are bent back alike or to the sameside and at substantially right angles and constitute the so-calledflanges or wings I. Then it depends on the use made oi? the bradswhether one or the other hecomes the inside.

The shoulders 5 on the ends oi the body 2 are oi such length as willsuiliciently spread the flanges 1: to use the brad as seen in Fig. 3 andhold the driving point as nearly as possible in line with the grain ofthe wood into which it is driven, the spread of the flanges relativelyas far apart. as shown by means of said shoulders enabling thisimportant ell'cot to be obtained and which would not be possible withthe requisite depth oi llango ii they came immediately at the base oilthe point and which would necessarily narrow the brad to such shortspace between flanges that it would throw the point at such a decidedangle across the grain oi the sash that it would be liable to split thesash. This occurs because the idle flange must rest on the glass whilethe other ilange is dropped down over the ed go of the glass.

What I claim is:

As a new article oi' manul'acture, a brad tor iastening glass in hot-bcdsashes having a V-shaped driving point and a body extending laterallyfrom the base ot said point at both sides and providing shoulders ateach side oi said base, and said body pro vided with flanges at its endsextending rearward at right an glcs to said body from the outer portionsof said shoulders.

In testimony whereof I allix my signature in presence oi. two witnesses.
